Medication details


Malorone es un tratamiento solo con receta. Contiene dos principios activos, atovacuona y proguanil, y pertenece a un grupo de medicamentos denominados antipalúdicos .

Malorone puede prevenir y tratar la malaria al matar cualquier parásito que ingrese al cuerpo. También puede matar parásitos en personas que ya han tenido paludismo.


Before embarking on your malaria-exposed journey, it is imperative to internalize the ensuing instructions. Malarone serves a dual purpose: the prevention and treatment of malaria. Depending on your specific objective, adhere scrupulously to the prescribed dosing regimen.


The efficacy of Malarone emanates from its synergistic active constituents—namely, atovaquone and proguanil hydrochloride. These agents are encased within the tablet's core, a blend of poloxamer 188, microcrystalline cellulose, hydroxypropyl cellulose, povidone K30, sodium starch glycollate (Type A), and magnesium stearate. Enveloping this core is a coating comprising hypromellose, titanium dioxide (E171), iron oxide red (E172), macrogol 400, and polyethylene glycol 8000, which facilitates optimal delivery.

Side Effects

While Malarone undoubtedly stands as a stalwart guardian against malaria, it is pertinent to acknowledge the potential for side effects. These can span a spectrum from mild to severe. Vigilance is essential to detect signs of severe allergic reactions, skin aberrations, gastrointestinal disturbances, and other sporadic symptoms. In the event of such manifestations, immediate consultation with a healthcare professional is paramount.


Prioritizing your safety is non-negotiable. Refrain from using Malarone if allergies to its constituents are evident or if severe renal impairment exists. Prudent consideration is warranted for those with the aforementioned conditions or if the weight of a child is below 11 kg. Equally significant is understanding potential interactions with concurrent medications. For expectant or nursing individuals, soliciting expert medical advice is indispensable before embarking on Malarone.
